Dollhouse Puzzle (Attic)

Hint 1 of 8:

Check the rules section -- the rules are pretty complicated here.

Hint 2 of 8:

There are two things you can do for the bottom section of the house: use
trial and error or read on for an answer.  You can probably think out your
solution, but I doubt it would be worth it.

Hint 3 of 8:

Try setting a round window to up, semicircular to right, rounded rectangle
to down, and a complete rectangle to left.

Hint 4 of 8:

You can do this by starting from the 6th window from the left on the bottom.

Hint 5 of 8:

Then use the directions from a few hints ago to guide you -- for example, you
need to move up once you start at the first window.

Hint 6 of 8:

Once you reach the second level of the building, you can use the rules
that you set for yourself previously to work out the answer.  You can only
pick your starting window; look at each of them and try to figure out which
one will work.

Hint 7 of 8:

Here come the answers for the next two stages:

Hint 8 of 8:

Pick the 3rd window from the left on the second stage.
